According to https://tools.ietf.org/id/draft-oscca-cfrg-sm3-01.html, SM3 always produces a 256-bit hash value. E.g., it says: "SM3 produces an output hash value of 256 bits long" and "SM3 is a hash function that generates a 256-bit hash value." I don't see any mention of "SM3-256". So why not just keep it as "sm3" and change hash_info.c instead? Since the name there is currently wrong, no one can be using it yet.
Question: Is 256 bits fundamental to SM3? Could there ever be a variant in the future that's e.g., 512 bits?
